The final set of values is used to configure the T1 parameters. The line type allows you to select
Extended Super-Frame (ESF) or D4. ESF format is the standard format for ATM/T1
applications. D4 format is supported as an alternate; however, T1 signaling capabilities may be
limited. Check your network plans for a definition for your specific application.
line type : esf [esf|d4]
Additionally, you must choose a line coding type:
line coding : b8zs [b8zs|ami]
The approximate length of the T1 line is specified next. It is used to control the signal
conditioning used on the T1:
line length (ft) : 500
Finally, the T1’s timing source must be specified. A T1 uses only one timing source either at the
near-end or far-end of the line. You may select the BTS as the originator of the timing source by
selecting “local”, or you may select the far-end as the timing reference by selecting “loop”.
line clock source : loop [loop|local]
IMA Configuration
If you decide to utilize IMA groups to pool the T1 resources, then the same parameters described
for the ATM/T1 Configuration above also apply to configuring IMA’s. Refer to Exhibit 5.

In addition, the ATM interface must be specified as IMA and reference one of two IMA groups
used for the Management PVC. This IMA group must match what is identified in the EMS. Use
“0” for the first group and “1” for the second group.
